Issue/Introduction
This article provides information vCenter Server 4.1 network port requirements.
Environment
VMware vCenter Server 4.1.x
Resolution
The vCenter Server system must be able to send data to every managed host and receive data from every vSphere Client.
vCenter Server requires that these ports are open:
| Port | Description |
| 80 | Required for direct HTTP connections. Port 80 redirects requests to HTTPS port 443. |
| 389 | Active Directory Services for the vCenter Server group |
| 443 | Listens for connections from the vSphere Client, vSphere Web Access Client, and other SDK clients. |
| 636 | SSL port of the local instance for vCenter Linked Mode. |
| 902 (UDP) | Used to send data to managed hosts. |
| 902/903 | Used by the vSphere Client to display virtual machine consoles. |
| 5989 (TCP) | CIM transaction traffic (Hardware Status) |
| 8080 | vCenter Management Webservices HTTP. |
| 8443 | Secure connections for vCenter Management Webservices HTTPS. |
| 60099 | Used to stream inventory object changes to SDK clients. Firewall rules for this port on the vCenter Server can be set to block all, except from and to localhosts if the clients are installed on the same host as the vCenter Server service. |
